Hey guys hows it going first post on forum...........I am helping the service writer at the dealer I work at install a  "Vision X" HID kit. That is all i know about the kit....... the prob he is having is that when he hooked everything up the HID'S are inop. and he gets a code in the fcm/ipm for right front low beam resistance high. Which is why he came to me today to ask what I could do. This is what i came up with..... on the 06' WK and pretty much all of our (DCX) newer cars all of the lamps are sent a diagnostic 12v/0amp with the headlamps off to monitor for lamp and wiring issues. This diagnostic 12v is just that alone..... no amperage so if u put a test light to the connector key on head lamps off the test lamp will not illuminate, but will show the 12v on a dvom. So my problem is that the fcm is seeing the higher resistance of the conversion kit and only sending the diagnostic 12v/0amp. So the lamps will not illuminate. Basically i need to convince the fcm/ipm that the factory bulb is still in the veh.

I love the challenge of electrical problems, but the kit has no diagram just "PLUGS RIGHT IN" yeah right?????  So I am coming to the pros hoping to get a relay setup or wiring diagram to aid this installation. If need be I can e-mail all wiring diagrams.

Either way thanks for any assistance at all........

Dont know if this will help the resistance of the factory bulb is 1.5-1.8 ohms..........thanks again

They are NOT plug-N-play

use a relay, and connect pin 87 to the battery...fuse it @ 20 amps

pin 85 would be a NEG(-) trigger from your headlight harness

pin 86 will be 12volts fused

30 will go to your HID turn on.

Use at least 10 guage wire...............

Them damn things are REALLY unstable to voltage/current changes.

i did this car about 6 months ago a 2006 srt8 grand cherokee, we used a special ballast that showed the correct resistance to the car side . the way to fool the car is by adding in a relay and make then turn on like how kartuneman said to do it.

i am just confirming his reply from my own experience.

I learned this the hard way on my own car aswell. Plug-n-play on an 06 civic. No-workie!  What sucked about my ride was, to access the bulb, you go thru the fender well. Just to get to the bulb. Jack stands, air gun.....etc. Then one of my relay slid down from where I had it zipped....and filled with water.Yikes!!

I wrote this for the SRT8 forum, but it applies to this topic.

Flickers of the HID bulbs are caused by a low current 12v signal that the vehicle puts through the bulb even when the lights are completely off. This will help the ECM recognize when a bulb is burnt out. To test this you can hook back up one standard bulb on one side and leave the HID on the other. With the lights shut off, the standard bulb will not light, but the HID may flicker occasionally. This is bad, very very bad, for the HID system! It will burn it out in months.

I think a relay will fix the problem, I am not sure if each side needs a relay, but thats how I am going to wire it. To accomplish this, from the stock headlight wiring you have two wires, one of these will go to pin 86 on the relay and the other to pin 85. Doesn't matter which goes where because this is a simple coil that drives the relay and it doesn't care. Next, run new power cables from the battery to pin 87 on the relay (Make sure to fuse this close to the battery 15 or 20 amps per side will be plenty and will prevent a fire). Pin 30 will now go to the + supply on your HID system, usually red or anything but black, but check the wiring diagram first!! Finally connect the - of the HID system to a solid vehicle ground. I would recomend using at least a #12 wire for everything to ensure you have enough supply current w/o heating.

This should trick the system into thinking there is a good bulb, the relay's coil will provide about 100ohms of resistance, not as low as a real headlight, but better than the high impedence of looking into a HID ballast.

It would be wise to disable the AUTO headlight mode, because this mode turns the lights on and off throughout the day and also can keep them on while the vehicle is starting. All of these conditions are bad for HID ballasts.

Oh also if you have a Canadian version or any other version that has been modified to use daytime running lamps, this must be disabled. This involves a quick free trip to the dealer to set the correct country code in the ecm. If the DRL circuitry is activated, it provides 5-9 volts to the lamps during the day which would mean dim driving lights, but with a HID system it means a hot and burnt out ballast.

UPDATE:

The relays work like a charm, still make sure that you don't use the Auto mode. Instead use the manual mode because this will ensure that your HIDs will last for years instead of months like I have heard of happening.

The lights look great, soo much more light than stock.

If anyone has questions please send me a message and I will try to get back to you quickly.

Final thought, if you are going to do both the Highs and Lows (A total of 4 ballasts) you wont be able to quickly flash your brights anymore because it will greatly reduce the lifespan of your HID highs.
